Output
Description
4 to 20 Milliamperes (Standard)
• The linear 4 to 20 mA output:
– corresponds to the field-programmed gas range.
– can be calibrated in the field for maximum accuracy.
– is user selectable for isolated or non-isolated use.
Refer to the “Setup ” section for programming information.
4 to 20 mA with Relays (Optional)
• Option includes a set of four relays:
–High Alarm
–Low Alarm
–Auxiliary Alarm
–Fault
• The High, Low and Auxiliary Alarm relays are programmable
as a group for either normally energized or normally de-energized
operation.
• Low Alarm, Auxiliary Alarm, and High Alarm relays are programmable as
a group for either latching or non-latching operation.
• Fault relay is normally energized with no faults. Faults are generally
non-latching, but faults that occur during calibration and warmup must be
reset.
• Latching relays are reset using either the Cal magnet or an external reset
switch (field installed, user supplied).
